Comparative Study Clinical Trial
Post-thymectomy combined treatment of prednisone and tacrolimus versus prednisone alone for consolidation of complete stable remission in patients with myasthenia gravis: a non-randomized, non-controlled study.
Thymectomy is a standard treatment of myasthenia gravis (MG). Immunomodulating agents are frequently given during the post-thymectomy latency period until complete remission is fully consolidated. ⋯ Post-thymectomy administration of tacrolimus combined with prednisone was more effective than prednisone alone for the consolidation of CSR in a substantially shorter period of time in patients with MG.

Randomized Controlled Trial Comparative Study
Bioavailability of triple-bead mixed amphetamine salts compared with a dose-augmentation strategy of mixed amphetamine salts extended release plus mixed amphetamine salts immediate release.
To compare the single-dose pharmacokinetics of triple-bead mixed amphetamine salts (MAS), an oral, once-daily, enhanced extended-release amphetamine formulation, with MAS extended release (MAS XR) (Adderall XR) + MAS immediate release (MAS IR) administered 8 h later. ⋯ In healthy adults, the exposure observed with triple-bead MAS 37.5 mg was bioequivalent to MAS XR 25 mg supplemented by MAS IR 12.5 mg administered 8 h later. These data demonstrate that a single morning dose of triple-bead MAS provides equivalent plasma concentrations to those observed with a dose-augmentation strategy of MAS XR in the morning followed by MAS IR in the afternoon, while minimizing peak-to-trough fluctuations. Triple-bead MAS was also generally well-tolerated in this study.

Options for lowering testosterone in patients with prostate cancer include bilateral orchiectomy, oestrogens and luteinising hormone-releasing hormone (LHRH) agonists. LHRH agonists have become widely used in the treatment of prostate cancer. ⋯ LHRH agonists should be considered first-choice testosterone-lowering therapy for the treatment of prostate cancer, with the 3-month depot formulation providing optimal convenience and flexibility. Assessment of patients receiving LHRH agonists should be based on PSA levels rather than ST levels, although levels of ST similar to those obtained after orchiectomy still need to be achieved. Further studies are warranted before the potential therapeutic benefit of considerably lowered ST levels can be fully assessed.

Multicenter Study Clinical Trial
Efficacy and safety evaluation of once-daily OROS hydromorphone in patients with chronic low back pain: a pilot open-label study (DO-127).
To evaluate the safety, tolerability, and efficacy of once-daily osmotic controlled-release oral delivery system (OROS) hydromorphone in patients with chronic low back pain of moderate-to-severe intensity. ⋯ OROS hydromorphone may be an effective treatment for chronic low back pain of moderate-to-severe intensity. Adverse events were typical of those associated with opioid therapy.
